When I flew from Zurich to Vienna with my sister she knew the purser of the flight.
While she was immediately seated in business class I was asked if I would mind to enjoy the entire flight in the cockpit on a jump seat
(yeah, I know: stupid question :) )
Even though I was in my late 20s it was a kid's dream come true.
Needless to say that this was before 9/11 and that this would be completely impossible nowadays.
Which is a shame.
Imagine about seven quite massive ring binders on the floor on the right side of the first officer.
Today they probably have that all on an iPad. I could imagine, though and given how conservative the aviation industry is, that they still have to lug around the entire amount of paper.
That, however and admittedly, is just a guess.
I flew to a conference in Vegas last month on a 737 (via Southwest). Chatted a bit with the pilots and was reminded how cramped the cockpit is these days. Even with multi-function displays, there were a billion levers/buttons/knobs. How they ever were allowed to have a hyper-curious kid in the cockpit back in the day is unthinkable.
